Green Plains Renewable Energy, Inc. announced today that it will implement corn oil extraction technology at its ethanol plants. The Company expects to complete the technology deployment by the end of the first quarter of 2011 and anticipates the project would enhance operating income by $15 million to $19 million per year.

"Our objective is to continue to diversify our cash flows and to de-risk our overall platform," said Todd Becker, President and Chief Executive Officer of Green Plains Renewable Energy. "This project allows us to realize additional income streams from value-added co-products. The production of 75 million to 90 million pounds of corn oil per year will generate substantial recurring free cash flows and excellent returns on invested capital."

ICM, Inc. has been awarded turn-key installation contracts at five of the Company's six plants. The expected total project cost for all plants is approximately $18 million. The Company anticipates first revenues from corn oil extraction at the Obion, Tennessee plant to occur within the next 90 days.

Green Plains has entered into a license agreement with GS CleanTech Corporation, a subsidiary of GreenShift Corporation, to utilize its patents and pending patents.
